VERTICALLY-SLIDABLE INWARDLY-SWINGING WINDOW.

Application led July 5,

T o all 'whom z't may concern.'

Be it known that I, OWEN L. DAUTRICK, a citizen ofthe UnitedStatcsresiding at Detroit, county of l/Vayne, State of VMichigan, haveinvented a certain new and useful Improvement in Vertically-SlidableInwardly-Swinging indows'` and declare the following to bea full, clear,and exact de scription of the same, Such as will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention relates to an attachment for vertically slidable windowsash whereby the sash may be swung inwardly for convenience in cleaningthe outer face of the glass, as shown in the accompanying drawings andmore particularly described in the 'following specification and claims.i It is well known that inv large otlice or apartment buildings theproblem of cleaning windows is one involving considerable an nualexpense due to the time required and the hazardous nature of the work.

The primary object, therefore, of the present invention is to provide anattachment for vertically movable window sash whereby the glass may bequickly and readily cleaned from the inside of thebuilding, therebygreatly reducing the risk incurred by the party cleaning the windows andthe time required to do the work. c

A further object of the invention is to provide suitable metallic guidesattached to the window casings adapted to co-act with elements'carriedupon the edge of the sash in order that the vertical movement of thesash may be facilitated and whereby the tendency and casing.

to bind, common to ordinary sash in which two wood surfaces lie incontiguous relation 'is overcome.

A further object of the invention is to provide a close fittingoverlapping construction thereby preventing the entry of drafts incidentto the use of the ordinary wood sash .embodiment of the invention hereindis- 1924. Serial No. 724,316.

closed without departing from the spirit of the same.

ln the drawings accompanying this speciication: A

Figurel is a fragmentary front elevation of a slidable channel memberadapted for attachment to the usual sash cord connected with the lowerdetachable. end of said slidable channel member.

Figure 2 is a longitudinal sectional r)view taken on 'or about line 2--2of Figure l showing the lower sash frame pivoted to the detachable endof the slidable channel member; the detachable end of the channel memberbeing engaged by a latch carried by the body portion of said member. l.

Figure 3 is an enlarged4 view of an upper fragment of the channel membershown in Figpre 1, engaged to the loop of a sash cor Figure 4 is a'longitudinal sectional view through the slidable channel member, taken0n or about line 4 4 of Figure 3,-connected with a sash cord.

Figure 5 is a cross-sectional View of the slidable channel member, and aco-acting guide or track plate secured to the window casingthe winldowcasing and sash frame being shown in dotted lines.

Figure 6 is a fragmentary perspective View of one of the slidablechannel members with parts broken away showing a fragment of the sashframe pivoted to the lower detachable end of the channel member.

Figure 7 is a fragmentary perspective view with parts broken away and insection showing the lower sash swung into locked alignment with theslidable channel member that it may move vertically therewith.

Figure 8 is a fragmentary perspective view showing the lower sash swungintoy a room for cleaning, and the upper sash and channel frame-to whichthe latter is pivoted, lowered that it may be swung below the ends ofthedetachable slidable channel members of the 'lower sash,-indicated by thedotted lines, the full lines showing the upper vsash vand upper channelmembers raised in order that the upper sash may tilt over the detachablelower end portions of the channel members supporting the lower sash, asit would appear when about to be laidl upon the lower sash.

Referring now to the letters of reference placed upon the drawings:

A denotes a lower sash frame to the side members of which are securedplates A pivoted at Aa to a relatively short channel member B carryingan upwardly projecting tongue Bb having a beveled end Bbb projectinginto a. relatively long vertically movable abutting channel member C,that the detachable channel member B may be held in locked relation withthe latter by a spring latch D, fitted with a stud Dd adapted to enteran aperture b1 provided in the tongue B1 riveted or otherwise secured tesaid lower detachable channel cmember/ B.

Projecting -inwardly from the channel member C is a tongue C1 adapted toreceive :11.1 loop E attached to a weighted sash cord Pivoted to theupper end of the channel member C is a spring actuated latch F adaptedto engage a latch plate G secured to the side members of the sash framenear their upper ends to lock the sash in alignment with the vertically`movable channel member. C2 indicates a second tongue struck up from thebody of the vertically movable channel member C and extending laterallyto overlap the latch plate G to assist t-he latch F in maintaining thesash in proper alignment with the vertically movable channel membersz-the side members of the sash frame being cnt away to permit the tongueto pass beneath the latch plate as indicated at Figure A2.

H designates a guide rail secured to the side members of the windowcasing having iianged edges HHHa in spaced relation to the window casingto receive the inwardly directed edges Ca of the channel member C,forming a draft-tight joint with the flange ll of the guide rail. Thechannel member C is also provided with a projecting flange Cb adaptedtooverlap the side member of the sash frame against which the sash istightly held by the spring latches F.

Having now indicated the several parts by reference letters theconstruction and operation of the device will be readily understood:

lVhen it is desired to swing the lower sash inwardly to clean theoutside of the glass,

the sash if raised is first lowered. the latches l" pivoted to theslidable channel members are then released to permit the lower sash toswing inwardly on the pivots A, projecting from the lower detachablechannel members B, whereupon the outer face of the glass may be readilycleaned 'from the inside ot the building.

To clean the upper sash the channel members CC of the lower sash arefirst disconnected from the Ilower detachable channel members BB byreleasing the stud Dd carried by the spring latches D from the aperturesb1 in the tongues Bb.. The channel members CC are then lifted under Atheaction of their respective counterpoised weights to the positionindicated in Figure S. The upper sash is then lowered until it touchesthe sill-as indicated in dotted lines in said figure. The sash is thenreleased from the control of the spring latches Fx, that it (the sash)may swing below the vertically Inovable channel members CC, as indicatedin dotted lines in the figure. The upper sash is then raised slightly tothe position shown in full lines in order that it may swing over thcllower detachable channel member B",-

whereupon it may be lowered so as to rest. upon the lower sash that theoutside of the glass may be readily cleaned.

After cleaning the windows the upper sash' is swung back into .itsinitialposition in alignment with the upper movable. channel membersCXCx slidable on the guide rails Ilxthe sash being secured in alignmentby the spring latches F". It will be understood that the construction ofthe channel members and cooperating parts of the upper sash aresubstantially similar to those of the lower sash.

Thechannel members CC of the lower sash are. then lowered into lockingengagement' with the detachable lower ends B. The lower sash is thenswung-back into its initial position in its channel members` to which itis again locked by the spring latches F. The sash frames are then incondition for operation as usual, or until the windows are to be cleanedagain.

Having thus described my invention what I claim is:
